Who Can Update GST Registration Details on the Portal?

The following individuals and entities are eligible to make amendments to GST registration details:

Registered taxpayers, including new registrants

GST practitioners
OIDAR service providers (Online Information and Database Access or Retrieval)
Non-resident taxable persons.

Core vs. Non-Core Fields in GST Amendment

GST registration details are categorized into Core and Non-Core fields. Understanding the difference helps determine whether approval from a GST officer is required.

Core Fields (require approval):

Legal name of the business (PAN must remain unchanged)
Principal and additional places of business (excluding changes across states)
Addition/removal of stakeholders (e.g., promoters, partners, Karta, managing committee members, CEO)

Non-Core Fields (auto-approved upon submission):

Bank account details
Business details (excluding core identifiers)
Description of goods/services
State-specific details (if within the same state)
Authorised signatory details
Edits to existing stakeholder info
Minor edits to address within the same place of business

If a core field amendment request isn’t addressed by the tax officer within the stipulated time, it is auto-approved.
